This research was conducted in Rio Verde Campus Echeandía belonging to Canton, Bolivar Province, Ecuador. PRE has a very humid montane forest (bmhPM). With rainfall of 2500-3000 mm. With a water deficit less than 250mm., Drought in July and December, January and March rains, strong sun August, January and February wind. The objectives were: • Diagnose and botanical characterization of medicinal plants in the agro-ecological zone of Rio Verde. • Characterize morphologically to each of the relevant medicinal plants in the area. • Develop a botanical inventory of existing relevant medicinal plants in the area. To collect this information, a questionnaire with clear and easily understood questions aimed at 50 local families, after obtaining the diagnosis of medicinal plants sector, in the laboratory was characterized morphologically using the stereo microscope was applied organs was observed vegetative; type of inflorescence, flower, fruit, seed and flower shape of each of the samples obtained in the field. A description of farmers was conducted in relation to the gender of the household head, identification, knowledge, existence, amount, sites and use of medicinal plants in the study area. And diagnosis and morphological characterization of medicinal plants that dominate the sector Rio Verde. Existing and prevailing in the medicinal species are found in the wild and / or cultivated, taken into account the ten relevant plants that characterization was performed more frequently use guabiduca, basil, guava, lemon grass, grass good, plantain, mastrante, mint, lemon balm and verbena, because they are wild medicinal plants that provide multiple uses. The genre of farmers / as in the sector. 44% women who know of existing plants within the estate, 40% men. And some 16%, as the case of grandparents brothers guys are acting as head of household in the absence of a parent. 38% of the families surveyed have planted herbs in their gardens around their homes, in order to have greater access to them and 12% have not sown, meaning that most people retain this resource. 100% of the families living in the area known existing medicinal plants. The consumption of most plants is in infusion, juices and extracts is the so fewer farmers consume medicinal plants. 100% of inhabitants indicate that some species of medicinal plants that previously existed are disappearing. Most notable was the interest of the peasants-as conserve medicinal plants in their gardens, fences or around their homes, so to access them more easily when they need it. Give them the benefit these families medicinal species of this sector are purely curative, to relieve stomach pains, fever, shock, infections, inflammations, cramps ghosts prepared extracts, plasters and clean.

Renewable the natural resources water, ground, vegetation and air are the goods of the nature that allow the processes of the life and development In the world every year the forests are reduced; according to the FAO (2003), In our country, the degradation of renewable the natural resources is constant. The deforestation with an annual rate of 163,400 hectares En Ecuador exists approximately 10.557.000 hectares of forests the grass surface has been increased in the country in decline of area of natural forests, the natural vegetal cover has been replaced by different types from uses, like (cultures, grass). Diagnosing the present state of the existing natural resources in micro Charquiyacu river basin of the Echeandía Corner, the boundary of the microriver basin and identification on the use of the ground and hydric network. Knowing the existing production systems in the microriver basin. The identification of the main species of existing flora and fauna in the microriver basin. And determining the hydric availability of the microriver basin. Yacu.se is the objectives of this investigation the present investigation was made in the Province Bolivar Echeandía corner Charqui sector I use the following materials Altimeter, Podadora, GPS, Rain gauge, Lisímetro, Equipment of Software. ArcView GIS 3,2 for the maps Microsoft Office. The methodology which I am applied in I diagnose is the one that is used to study a community or vegetal association within a microriver basin or geographic unit. In order to analyze the data taken from field, a simple program of descriptive statistic, Correlations and regressions. Obtained results the microriver basin Charquiyacu is located to an altitude that goes from 561 ms s.n.m to 1430 ms s.n.m. This area has a surface of 200.5 has is between the following edges: North: Miguel Espi'n and Aníbal Rosero (foot) where exist cultures associate and pastizales. The south: Gualberto Bonilla (head) mountain. This: Aníbal Rosero and Gualberto Bonilla (a flank) Mountain the West: School of Pángala (another Flank) pastizales. One determined that the microriver basin is of form type canelón in where 3 points of main affluence with 8 affluents of second order exist and 2 of third order Within the microriver basin exist 12 proprietors of the 200 earth that occupy 5 is the proprietor who has more land extension is Mr. Jose Villares with 32 has, the predominant production system is the grass with 58,85% of the surface of the microriver basin and 12,22% of natural forest and surpluses of forest.519 animals within the zone of influence exist altogether of which 24,08 % are of cattle in which it talks about arboreal vegetal species we have are 16 different species in where the species predominates chicken eye in which it talks about the shrubs we have to Asan, mountain Coffee and black Chilco that is those that but predominates in the zone you boil Them or crawling species that exist are Roast crawling, Palama, Mote of mountain, Bed I scream, the wild fauna we can say that 12 species of birds exist, Identified 5 species of mammals, being the species with greater I number of 8 animals is the Squirrel the identified reptiles that it has greater I number of animals is the Small lizard the amount of precipitation quantified in the microriver basin is of 566.4 mm by square meter in average at rainy time unlike the 63.23 mm by square meter at dry time these differences clearly must to the climatic factors. The volume of the water that happens through the volumes of the Charquiyacu river basin at the rainy time is in average of 39 liters per second unlike the volume of water that flows at the dry time that is of 25.36 liters per second in average this must to the amount of precipitation presented/displayed at the different times in the zone. An annual average of the hydric availability that offers the microriver basin of Carquiyacu is of 16,16 ltrs/seg. In summer ltrs/seg offers an average of 18,66.

The moral fine (Chlorophora tinctoria), it is a specie of a great importance at world level from the social, cultural, economic and environmental point of view. The indiscriminate pruning and the inadequacy of sustained programs of forestation pun in risk the existence of this species and many others. One of the factors that determine the low productivity of this specie is the short viability that presents the seeds, the unfavorable environmental conditions, and the insufficient knowledge of the benefits, for what it is necessary to evaluate the sexual propagation of this specie in different bases and gibberellic acid dose in nursery stage. This investigation was carried out in the canton Echeandía to 6 km road to Guaranda to an altitude of 600 msnm osl, with a temperature average of 18o C and an annual precipitation of 2500 mm. The objectives established in this investigation were:  Determine the most excellent agronomic characteristics that present the plants in each one of the treatments.  Study the effect (answer) of the gibberellic acid on the sexual propagation of fine morals.  Determine the best type of basis to obtain the best germination percentage.  Carry out an economic analysis cost/benefit. A complete blocks design was used DBCA at random in factorial arrangement plus a sample 3x3+1 with there repetitions. The A factor corresponded to there types of bases: A1: black soil plus bark of rice, A2 black soil plus guabos soil plus bark of coffee. The factor B corresponds to three gibberellic acid dose: B1: 100 ppm, B2: 200 ppm and B3: 300 ppm of gibberellic acid, 9 treatments were obtained plus a sample with three repetitions with a total of 30 treatments. The chemical of the bases, variance analysis, test of Tukey to 5%, simple analysis of correlation and simple regression and economic analysis were made. The germination of the seed of this specie is from 80 to 100% provided you sow it on time and with an appropriate treatment. As for the control of plagues and illnesses was carried out with Lynx for the earth and the rest was controlled in a homemade way, putting in practice insecticides, fungicides and trap for insects adults were guided to the organic control, in a nursery tree is more efficient this methodology in the definitive place it become more tedious this type of controls.

This investigation I was realized in the Charquiyacu micro-hollow located to 4 km of the Echeandía corner from the Bolivar province to 1200 m.l.s. with a temperature average of 22°C, and an annual average precipitation of 2300 mm, where the following objectives considered: i) To elaborate a diagnosis of the present situation of the micro-hollow, II) To realize an inventory of Flora and existing Fauna in the Charquiyacu micro-hollow and III) Elaboration of a map of Zoning of the Charquiyacu micro-hollow. In order to successfully obtain the information surveys, rising 100% were used altogether (12 families). For the analysis of the information descriptive statistic was used that both allowed the identification of more excellent production systems of the micro-hollow. In relation to the social area we can notice that the familiar nucleus this composed by 51% of men 49% of women. In the micro-hollow of the Charquiyacu river the main production system is sugar cane – and grasses Where agriculture is the predominant activity and more of 69% of the economically active population is dedicated to her, and its level of education consists of 91% to primary and secondary education whereas 9% correspond to education superior; in addition the Earth possession or use we found that 55% are of pastures (pastures), followed of the 14% of primary forest and surpluses of forests, whereas 31% we found cane cultures of sugar, banana, orange, coffee, Guinean and yucca, these are as well associate to each other. The 55,2% of the total of the population inhabit within the micro-hollow and the 44,8% of the population to migrated to other places for reasons of work and studies. In agreement to the economic aspects within the Charquiyacu micro-hollow we have 75% depends on the agricultural and cattle activity (species majors, minors) and 25% of the income are with manpower (wage), same that are distributed in the basic feeding, education, health, services, clothes and intermediate consumptions of production means. In the Charquiyacu micro-hollow they have a total entrance by the existing activities of production in the area in study (agriculturist, cattle and sale of manpower) is of 155741.6 USD and a 132499,9 debit of USD/año, with average of 1.28USD/día by familiar member. In conclusion it means that by each hectare of the different activities that execute in their production systems this cattle 0.077 USD, existing a deficient value to satisfy the basic needs The agro-ecological Zoning identified the best alternatives of sustainable use of the micro-hollow as it bases technique for his ordering and the advantage of his resources, being this 51.58% of the surface that needs rehabilitation activities in the fragile zones. The results of the morfométricos analysis of the Charquiyacu micro-hollow give an area us of 200.50ha and a perimeter of 6.11km its form is extended with little danger in the days of rain and its direction goes of this the west, owns an order of 3 current and one densidad of drainage of 4.76Km; the maximum precipitation is of 606.7mm and a minimum precipitation 27.2mm. With respect to the flora we have were 20 forest species and 12 predominant bush species like husk, end of axe, fine moral, black stupid moral cedar red, colca and chilco, caddy, straw toquilla. In relation to the fauna we have 25 species of fauna (birds and mammals) wild where but accentuated they are the mount guinea pig, cusumbo, tile, squirrel, rustic sparrowhawk and guatusa and the monkeys due to the destruction of their nutritional chain species them in extinction danger fears guanta to us

Tillage systems and conservation agriculture worldwide is still highly regarded within the management as an alternative source of protection for natural resources in Ecuador sustainable agriculture alternatives, is a sound management practice, despite these becomes difficult to incorporate technologies to farmer's practices because of this problem, the soil resource is exploited to a point beyond which activities such as overgrazing of livestock, agricultural production in marginal areas, involving not only the degradation natural capital, but also to socio- economic impacts on farming families. This research was conducted in the watershed of the river Illangama, Bolivar Province, at an altitude of 3500 meters; the type of soil was silt loam, MO with 8.05% and a slightly acidic pH of 6.3. The goals that emerged from this research were: i) Assess the medium term effect of two tillage systems, land use and fertilization on the potato crop on the physical, chemical and biological soil properties. ii) Determine the effect of tillage systems, land use and fertilization on the yield of the potato crop. iii) To conduct economic analysis of the implementation of farming systems, land use and fertilizer in potato cultivation. We used an experimental design of randomized complete block (RCBD) with 3 replications and 4 treatments. T1: Pasture with removal, conventional tillage, potato fertilization, T2: Pasture with removal, reduced tillage, potato fertilization, T3: Pasture without removal, reduced tillage, potato fertilization, T4: Pasture without removal, reduced tillage, potato except nitrogen fertilization (N). Were carried out chemical analysis of soil before planting, analysis of variance, Tukey test at 5%; partial budget economic analysis and calculation of the marginal rate of return. The main results obtained in this study were significantly influenced treatments, mainly in the analysis of variance for variables: root depth in cm, total yield in t / ha and dry matter of biomass in t / ha. The highest average yield of potato was assessed at T1: pasture with removal, conventional tillage, potato fertilization, but with a higher marginal rate of return on T3: Pasture without removal, reduced tillage, potato fertilization, because it reduces 76% of costs in preparing the ground. Economically treatment with the highest average value of the TMR was the T3: 804% and net income of $. 1832/ha, taking into account only the costs that vary with each treatment. Finally, 71 this study has contributed in reducing the processes of soil erosion in hillside agriculture through conservation tillage and crop nutrient efficiency

The systems agroforestales are guided to allow productive activities under conditions of high fragility, with degraded natural resources, by means of an efficient economic administration, altering to the minimum the ecological stability, that which contributes to reach the sostenibility of the production systems. The investigation was developed in the place Galápagos, canton Echeandía, Bolívar province, to an altitude of 910 m, temperature average of 22oC, precipitation average of 1800 mm. The objectives were: i) Settle down and to evaluate two systems agroforestales agronomical with base the cultivation of cocoa; ii) Evaluate the morphological characteristics and to determine the growth that presents the cultivation of cocoa in each system agroforestals cocoa in the first year of investigation. It was used two systems agroforestales: Triplaris guayaquilensis Weddell and Inga edulis with base of cultivation cocoa. Was carried out statistical analysis to determine the minimum value, maximum, average, relative frequency and percentage of the frequency. The evaluation was carried out to the beginning, 6 and 12 after established the systems agroforestals. The results of this investigation samples that the morphological and agronomic characteristics of the plants of cocoa inside the two systems agroforestales in this area agroecológica, were different for the main evaluated variables. At the end of the investigation the plants of cocoa in the system Triplaris guayaquilensis Weddell, reached a height average of 95,83 cm, with a maximum of 100 cm and the minimum 93 cm. In the system Inga edulis, the height average was of 86,50 cm, the maxim was 101 cm and the minimum 50 cm. To the 12 months, the minimum value and maximum of the diameter of the shaft of the base cultivation inside the system Triplaris guayaquilensis Weddell, it was of 0,45 and 0,69 cm. In the system Inga edulis, the diameter average was of 0,56 cm, a minimum of 0,45 cm and a maximum 0,69 cm. The plants of cocoa of the system Triplaris guayaquilensis Weddell to the 12 months they reached diameter of glass of 69 109,00 cm and in the system Inga edulis was of 103,44 cm. In the system Triplaris guayaquilensis Weddell one had 98,00% apprehension and 91,00% of survival of plants of cocoa; in the system Inga edulis registered an apprehension of 95,00% and a survival of plants of 87,00%. The incidence of Broom Trims glass (Crinipellis pernicious) and Ant arriera (Atta cephalotes) in the base cultivation in the two systems agroforestales, he/she registered respectively to the 6 months with an average of 9,00% and 69%. The systems agroforestales allow us to achieve a stable agricultural production, the forest species by themselves provide other benefits like: food source, wood and they improve the fertility of the floors like it is the case of the guabo

In the world, you begin to look to the cane guadúa like an ecological alternative, since its use in several productive processes would reduce the impact on the native forests, because the guadúa can be a substitute of the wood. This investigation was carried in the Mirador, Echeandía city, Bolívar state, to an altitude of 600 mls. The objectives outlined in this investigative work were: i) Evaluate the effect of four bases and two fitohormonas in the asexual propagation of guadúa plants in nursery. ii) Determine the effect of four types of organic bases on the apprehension of guadúa plants in nursery. iii) Measure the answer of two types of hormones in the asexual propagation of guadúa plants in nursery and their effect in the apprehension components and survival of plants. iv) Carry out a budget economic analysis partially and Marginal Rate of Return (TMR%). A design of Complete Blocks was used at random (DBCA) in factorial arrangement 4x2. Factor A corresponded to four types of bases: A1: Earth of Guabo, A2: Humus of Worm, A3: Shell of Cocoa and A4: Earth of the Place. The Factor B was two types of hormones B1: Cytokin and B2: Rootmost. Eight treatments were had with three repetitions. They were carried out variance analysis, main effect for types of hormones, test of Tukey for factor A, Types of bases and interactions AxB. Correlation analysis and economic of budget partially and calculation of the TMR%. The more important results were: The basis with the percentage of survival of higher guadúa to the 90 days was the A1: Earth of Guabo with 89,67%. The hormone with the biggest percentage of survival of guadúa plants to the 90 days was Cytokin with 79,17%. In the interaction of factors AxB, the highest percentage of survival in plants was evaluated in the T 1: A1B1 (Guabo Earth with the hormone Cytokin) with 90,33%. The independent variables that contributed to obtain a bigger percentage of survival of plants to the 90 days were: percentage of apprehension of plants to the 30 and 60 days, height of the bud to the 60 and 90 days, diameter of the shaft to the 90 days and root volume to the 90 days. Economically the treatment with the highest net profit was the T5: A3B1 (Shell of cocoa with the hormone Cytokin) with $. 44,48 and a value of TMR of 37%. Finally this study contributed to improve the asexual propagation of cane guadúa, 123 having plants of good quality, very developed and in smaller time, with 60 days less in relation to the one to conventional propagation, that makes more competitive the activity of the viverista

At world level the ecology is affected by the constant deforestation of the surface terrestrial year to year the arboreal masses they have come diminishing in some American countries Center and Tercermundista for the indiscriminate pruning of the forests, originating desertization processes and degradations of the floors; situation that worries the governments that are taking stocks tenements to the processes of preservation of the forests. The Melina (Gmelina arboreal Roxb) it is a forest species of quick growth and that he/she offers wide possibilities for the development of the reforestation One of the factors that subtract the productivity of this species it is the first floor percentage of germinative of the seed, being necessary to evaluate different methods pregerminativos and types of bases in the nursery stage. This investigation was carried out the experimental farm of the Agricultural Technical College "Sabanetillas”, of the Sabanetillas in the Main Parish of Echeandía to an altitude of 620 mls with a temperature average of 25 oC and an annual precipitation of 1400 mm The objectives that thought about in this investigation were: i) Determine which is the method more appropriate pregerminativo in their propagation. ii) Evaluate the best basis type to obtain the development of the plant. iii) The economic analysis of the partial budget and marginal rate of return. A Design of Complete Blocks was used at random in factorial arrangement 3x3+1 with three repetitions. The Factor A it corresponded to 3 Methods pregerminativos: A1: Scarification of the seed with nitric acid; A2: Treatment with hot water for three minutes and A3: I soak in cold water for 48 hours. The Factor B was 3 types of Bases: B1: 75% of vegetable garden earth more 25% of sand; B2: 75% of vegetable garden earth more 25% of pulp of coffee and B3: % of vegetable garden earth more 25% of sand and 25% of pulp of coffee. Ten treatments were had. Variance analysis was made, test of Tukey to 5%, correlation analysis and regression and budget economic analysis partially and TMR%. 145 The most outstanding results obtained in this investigation were: In the interaction of factors methods pregerminativos for types of bases, the effective treatments were the T7: A3B1 (Seed in soaking with cold water for 48 hours more basis 75% of vegetable garden earth + 25% of sand) and T9: A3B3 (Seed in soaking with cold water for 48 hours more basis 50% of vegetable garden earth + 25% of sand + 25% of pulp of coffee) with 96% of survival of Melina plants to the 90 days. The independent variables that contributed to obtain a percentage of survival of more vigorous Melina plants to the 90 days were: brotación percentage; height of plants to the 60 days; diameter of the shaft to the 60 and 90 days; number of leaves to the 60 and 90 days; wide of the leaf to the 60 days; longitude of the petiole to the 60 days and root volume in cm3.

In the Ecuador due to the populational increase is necessary the opening and improvement of highways, which cause big damages agroforestales; this happens when they are not carried out the studies of feasibility in the construction of the roads. The present study looked for to know the grade of damage agroforestal caused by the improvement of the road Guanujo - Echeandía, in which we can appreciate that the damage agroforestal is not very significant. The objectives that thought about in this investigation were: To determine the main factors the residents' of the margins of the road Agroforestales in improvement Guanujo - Echeandía. To analyze the obtained information based on the surveys. This study was carried out in the margins of the road Guanujo - Echeandía, in which was carried out the surveys to the residents of this area, using the stratified sampling. To gather the information he/she was carried out the survey directly to the house residents at home in the sectors of: Guanujo, Chalungoto, Atandahua, Candiushi, Cochapamba, The Glass, Tambo Real,Illuví, Capilluco, Palm Hill, Mulayaco, Lemon, The Dinner, The Painful one, Puruhuay, Shirahuan, Pitiambi, The Houses and San Vicente. The identification of the area was by means of a map satelital of the area in study provided by the Association Caminosca - Thesa, responsible for the studies of the road, in which was determined the sectors of this investigation. The survey was semi structured on the base of open and closed questions using a clear and comprehensible language. For the analysis of the study the statistical program SPSS was used. In this study you concluded the following: The lands of the residents are down in a great majority, reason why a minimum part is leased; these lands also have an irregular topography. In what refers to the land loss for amplification one has that in the stratum 1 80% of those interviewed lost 736 m2; in the stratum 2 93% of those interviewed lost 75 872 m2 and in the stratum 3 74% of those interviewed lost 820 m2; therefore we have that the stratum more you affect for the improvement vial it is the stratum 2. The residents of the Stratum 1, they possess the following cultivations: Pope and cereals (corn, barley, wheat), among the grasses we have: kikuyo, trenches and medic, of forest species is: Pines, Cypress, Eucalyptuses and Fences of Milkman and Tiupitian; in the Stratum 2 the cultivations prevail of: it lives and corn, the grasses that stand out are: Kikuyo and Elephant, of species forest Pines, Eucalyptuses, Fences of Chilca and Platuquero; and finally in the Stratum 3 the cultivations of more production are: Guinean, orange, sugar cane and banana, among the most excellent grasses are: Elephant, Saboya and Brachiaria, and of the forest species that possess they are: Fernán Sánchez, Platuquero, Motilón and Fences of Plum tree, Maté, Patevaca. Along the highway in study the following cultivations were affected mainly: it lives and cane; among the affected grasses we have: the kikuyo; and lastly the affected forest species are the following ones: Fences of Chilca, Tiupitian, Platuqueros, Milkmen, Plum trees, Matés and Patevaca. According to the residents of this sector diminished largely the forest production for the indiscriminate pruning of the trees. In the first Stratum of it determined that if it changed the texture of the floors because you mescla the stony materials with the arable earth; and in the Strata 2 and 3 they agree that it won't change the texture of the floors, because their lands are more inside the road. In the total itinerary of this via it has been determined that 42.13% of affectation exists in the resources floor and it dilutes. Finally in this investigation was demonstrated that in the improvement of the road Guanujo - Echeandía bigger destruction agroforestal doesn't exist in the margins of the same one
